atomic.cpp: fix rare overload scenario

If slot allocation fails, increase reference counter in every slot.
This prevents search routine from "losing" some slots.

atomic.cpp: optimize raw_notify() for unspecified pointer mode

Remove unnecessary optimization from cond_alloc().
Optimistic case was absolutely dominating anyway.
Although the whole function is a dirty hack.
Now scanning through all threads is faster.

Fix logic error in callstacks handling code, always set first to false after first iteration.
Add explicit check for zero return addresses. Current code validity checks may not check for it properly when it sits on interrupt handler entry point (which may contain valid code).
